Question 79775
Because these equations are given in standard form, it's easiest to graph each of these by the TWO INTERCEPT METHOD.  


x-y=-5

If x=0, then -y=-5, so y=5
If y=0, then x=-5


2x-6y=-18

If x=0, then -6y=-18, so y=3
If y=0, then 2x=-18, so x=-9


Graph these points and connect the respective dots!  It should look like this:

{{{ graph (300,300, -10,10,-10,10, x+5, (2x+18)/6) }}}
It looks like the graphs cross at x=-3 and y=2.  Therefore the solution set is the point { (-3,2) }
